General Description

The CT1995 Series is a monolithic implementation of the MIL-STD-1553B Bus Controller, Remote

Terminal and Passive Monitor functions. All protocol functions of MIL-STD-1553B are incorporated and a

number of options are included to improve flexibility. These features include programming of the status

word, illegalizing specific commands and an independent loop back self-test which is initiated by the

subsystem. This unit is directly compatible with all transceivers and microprocessor interfaces such as the

CT1611 and CT1800 produced by Aeroflex Incorporated.
